    Torque on an exoplanet from an anisotropic evaporative wind (2015)
    Oxford University Press
    Details
    Publication Date: 2015-07-18
    Description: Winds from short-period Earth and Neptune mass exoplanets, driven by high-energy radiation from a young star, may evaporate a significant fraction of a planet's mass. If the momentum flux from the evaporative wind is not aligned with the planet/star axis, then it can exert a torque on the planet's orbit. Using steady-state one-dimensional evaporative wind models, we estimate this torque using a lag angle that depends on the product of the speed of the planet's upper atmosphere and a flow time-scale for the wind to reach its sonic radius. We estimate the regime of planet radius, mass and stellar radiation flux in which a wind is capable of exerting a significant torque on the planet's orbit, and we find that it could be important for some of the observed planets. We also estimate the momentum flux from time-dependent one-dimensional hydrodynamical simulations. Similar to the Yarkovsky effect, the wind causes the planet to drift outwards if atmospheric circulation is prograde (super-rotating) and in the opposite direction if the circulation is retrograde. A close-in super-Earth mass planet that loses a large fraction of its mass in a wind could drift a few per cent of its semimajor axis. While this change is small, it places constraints on the evolution of resonant pairs such as Kepler 36b and c.

    Probing X-ray photoevaporative winds through their interaction with ionizing radiation in cluster environments: the case for X-ray proplyds (2014)
    Oxford University Press
    Details
    Publication Date: 2014-12-03
    Description: We show that if young low-mass stars are subject to vigorous X-ray driven disc winds, then such winds may be rendered detectable in cluster environments through their interaction with ionizing radiation from massive stars. In particular we argue that in the Orion nebula cluster (ONC) one expects to see of order tens of ‘X-ray proplyds’ (i.e. objects with offset ionization fronts detectable through optical imaging) in the range 0.3–0.6 pc from 1 C Ori (the dominant O star in the ONC). Objects at this distance lie outside the central ‘FUV zone’ in the ONC where proplyd structures are instead well explained by neutral winds driven by external far-ultraviolet (FUV) emission from 1 C Ori. We show that the predicted numbers and sizes of X-ray proplyds in this region are compatible with the numbers of proplyds observed and that this may also provide an explanation for at least some of the far flung proplyds observed in the Carina nebula. We compare the sizes of observed proplyds outside the FUV region of the ONC with model predictions based on the current observed X-ray luminosities of these sources (bearing in mind that the current size is actually set by the X-ray luminosity a few hundred years previously, corresponding to the flow time to the ionization front). We discuss whether variability on this time-scale can plausibly explain the proplyd size data on a case-by-case basis. We also calculate the predicted radio free–free emission signature of X-ray proplyds and show that this is readily detectable. Monitoring is, however, required in order to distinguish such emission from non-thermal radio emission from active coronae. We also predict that it is only at distances more than a parsec from 1 C Ori that the free–free emission signature of such offset ionized structures would be clearly distinguishable from an externally driven ionized disc wind. We argue that the fortuitous proximity of massive stars in the ONC can be used as a beacon to light up internally driven X-ray winds and that this represents a promising avenue for observational tests of the X-ray photoevaporation scenario.

    Rapid radiative clearing of protoplanetary discs (2016)
    Oxford University Press
    Details
    Publication Date: 2016-02-07
    Description: The lack of observed transition discs with inner gas holes of radii greater than ~50 au implies that protoplanetary discs dispersed from the inside out must remove gas from the outer regions rapidly. We investigate the role of photoevaporation in the final clearing of gas from low mass discs with inner holes. In particular, we study the so-called ‘thermal sweeping’ mechanism which results in rapid clearing of the disc. Thermal sweeping was originally thought to arise when the radial and vertical pressure scalelengths at the X-ray heated inner edge of the disc match. We demonstrate that this criterion is not fundamental. Rather, thermal sweeping occurs when the pressure maximum at the inner edge of the dust heated disc falls below the maximum possible pressure of X-ray heated gas (which depends on the local X-ray flux). We derive new critical peak volume and surface density estimates for rapid radiative clearing which, in general, result in rapid dispersal happening less readily than in previous estimates. This less efficient clearing of discs by X-ray driven thermal sweeping leaves open the issue of what mechanism (e.g. far-ultraviolet heating) can clear gas from the outer disc sufficiently quickly to explain the non-detection of cold gas around weak line T Tauri stars.

    A menu of moral issues: One week in the life of The Wall Street Journal (1992)
    Springer
    Journal of business ethics 11 (1992), S. 255-265 
    Details
    ISSN: 1573-0697
    Source: Springer Online Journal Archives 1860-2000
    Topics: Philosophy , Economics
    Notes: Abstract A “menu” of twelve moral issues that seem to be common to all organizations is described and illustrated. This “menu” identifies some of the most prominent moral issues requiring individuals to decide where to draw the line between moral and immoral conduct. A review ofThe Wall Street Journal during just one week provided over sixty articles illustrating how moral issues are inherent in almost every business decision. The articles included several illustrations of stealing, lying, and fraud that are immoral, although in some cases not technically illegal. Other articles illustrated conflicts of interest, influence buying, hiding information, divulging personal information, taking unfair advantage, personal decadence, interpersonal abuse, organizational abuse, rule violations, being an accessory to unethical acts, and balancing ethical dilemmas. These illustrations are intended to help individuals identify moral issues and recognize the situations when they arise so they can avoid unwitting immoral behavior.
